Was ill a few years back and slept for just over 24 hours, the weird thing is that my grandma says that I got up and went down stairs in a complete daze look in the living room, then went straight back to bed. Don't remeber that ever happening.

Got home from school at about 5pm, wanted to have a quick "nap" because it was my 17th birthday. Didn't wake up until 10am the next day and my family ate 'their portion' of my birthday cake. So like 15 hours and slept through my birthday...
